Thanks for the help, but the issue seems to have been a problem with my code because I am not having this issue anymore

Kind regards

Alright. I can try with a 10 x 10 cm square.

Appreciate your help :)

But is it possible that I have that problem exactly on each Start Node and nowhere else?

Regards!

Hi! Thanks for the reply. I dont think that that would solve the problem, becuase if I have to cut 2 ( or more) pieces, only one would be placed at 0,0 and not the rest. Am I correct?

Hey! The step per in mach3 is correct since if I make a square of 10x10 cm and run the code, the square measures are correct. I also used Mach3 tool that sets the "steps per" for you and gave me a...

Ok, so here are some pics of my machine, if more are needed please reply

@A_Camera I loaded the code you gave me but it measures 80 x 80 cm (bigger than my cutting area)

Thanks for the reply!

The Leadscrew is exactly this one. 5 is the number of starts the screw has.

Right now I am not where my machine is so I can't do much, but I will get some pics later...

I don't think so. The assembly manual didn't specify that bearings should be of that kind so I bought the "common" ones.



I dont understand what do you mean by this. I followed the assembly...

Wow thanks for all the replies :D

The details of my machine are:

I checked and there was a slight misalignment in the axis. I fixed it and also put a spring between the bearing and the coupling to prevent the screw from coming down....

Hey, thanks for the reply.

By hard I mean that if I try to manually screw it when the Lovejoy coupling is in it's right position, then it feels hard and requires me to do some strenght.

Does anybody know where can I get AB nuts 1/2"-8 8 start and thread clamps? Dumsptercnc doesn't make them anymore.

Best regards!

Impossible for my budget :(

Thanks for the help eman5oh.

So I guess that I will have to go with the 1/2-10 5 start, because I cant seem to find 1/2-8 8 start anti backlash nuts as dumsptercnc doesn't make them anymore.

Wouldn't lower resolution be fixed with microstepping?

I couldn't find the curves for the 381 so as both ger and eman suggested that this would be better, I will choose the 3rd kit.
The thing is that AT offer the kit with dual shaft or single shaft....

And how many of the Anti-backlash Leadnuts would I need? 3?

And I wouldnt need this two pieces

Hey ger, thanks for the input.

The leadscrew change you suggest is kind of budget killing for me. I could possibly go with the 1/2 10 5 start (about $39 on ebay, do you know where I can get them...

Thanks for the reply! I ouldn't find an answer googling, so what is motor inertia and what do you take into account to say that those motors have lower inertia?
